## Discrepancy

ENGINE NR 1, NR 2 & 3 FUEL FLOW INDICATORS READ ZERO AT TAKEOFF.  REMOVED CONNECTOR FROM PREVIOUSLY DEFERRED NR 3 ENGINE FUEL FLOW TRANSMITTER AND NR 1 & NR 2 ENGINE FUEL INDICATIONS OP CHECKED GOOD ON GROUND RUN.  THE FUEL FLOW POWER SUPPLY WAS REPLACED WITH NEGATIVE RESULTS.  ADDITIONAL TROUBLESHOOTING LEAD TO THE REPAIR OF WIRING.  OP CHECK GOOD BY FLIGHT CREW.
